• vpu-stride : Use 4 alignment for input height, to handle VPU buffer correctly. Note if it's enabled, input-crop are unavailable. : (default : false)

Pipeline example

Most of the properties are the same as that of v4l2src, below are rockchip extend properties:

• disable-autoconf : If false, this plugin will init pad format/selection for isp_subdev/sensor, to make the media pipeline work out-of-box: (default : false)
• tuning-xml-path : tuning xml file, needed by 3A : (default : "/etc/cam_iq.xml")
• isp-mode : "0A" to disable 3A, "2A" to enable AWB/AE, "3A" to enable AWB/AE/AF : (default : "false")
• input-crop : Selection-crop, should be "left"x"top"x"width"x"height": (optional)

NOTE: DO NOT RELY ON disable-autoconf=false!
This feature is only used to make debug conveniently.
rkcamsrc plugin is not designed as a CamHal. It's more like v4l2-ctl, just a simple capture program.
Since the use cases are divers, please handle media-controller and pad format/selection in APP level.
